Is solar power used in the mountains

The placement of solar panels on snow-covered mountains can boost the production of electricity when it is most needed — in the cold, dark winter.

A new study finds that installing solar panels on snow-covered mountains could help close the gap between demand and production during the winter months.

Solar power can also be efficiently produced in mountains and other cold regions - contrary to popular belief. The Himalayas and Tropical Andes are particularly promising locations for the development of solar energy, where installations could produce approximately 20 percent more energy than they could at sea level.

Solar power from the mountains has four advantages says WSL researcher Annalen Kahl: First, there are fewer clouds and less fog in the mountains during the winter. More sun means more energy. Second, solar radiation is higher owing to the snow cover in the Alps and can be efficiently used by solar plants.

Switzerland is leaning on solar in its nuclear power phaseout. AlpinSolar is part of a larger vision for Axpo, which says it aims to install 4,200 solar projects in Switzerland 's mountains.

6 FAQs about [Is solar power used in the mountains ]

Should solar panels be installed on snow-covered mountains?

The placement of solar panels on snow-covered mountains can boost the production of electricity when it is most needed — in the cold, dark winter. Solar-power systems have long been hampered by a seasonal problem: the panels produce more energy in summer than in winter, at least in the mid-latitudes, where much of the planet’s population lives.

Where can solar power be used?

In Nepal, for example, almost all remote airports and telecommunication facilities are powered by solar energy; solar cookers are widely used in the mountain regions of China and India. Wind power is a vast, but largely untapped source of potential sustainable energy in mountains.

Where can solar energy be produced?

How does snow affect solar power production?

The reflection from the snow helps solar power production at the AlpinSolar dam.REUTERS/Arnd Wiegmann Schranz says Switzerland's mountains are less affected by fog in colder months, meaning the panels see more sun than they would at lower altitudes.

Why do Switzerland's solar panels get more sun?

Schranz says Switzerland's mountains are less affected by fog in colder months, meaning the panels see more sun than they would at lower altitudes. "The reflection from the snow also helps," Schranz says, adding that "solar panels like the cold and have a higher yield in cooler temperatures."

Do solar panels produce more energy in winter?

Solar-power systems have long been hampered by a seasonal problem: the panels produce more energy in summer than in winter, at least in the mid-latitudes, where much of the planet’s population lives. To meet the goal of drawing 100% of energy from renewable sources, planners need to find ways to increase winter output.
